Question: Hi,

I've been suffering with chronic eye strain since last August (2012).

Lately, since maybe a month ago, I've been getting a random stinging sensation in my left eye (it's like briefly being poked with a needle, generally it only causes very brief pain). I'm wondering what this could be. Last visit to a doc was last November (2012) to see an optometrist. Pictures were taken of my eyes, nothing serious was found, other than a scar on the bottom of my left eye which had been seen the visit before it (beginning of October 2012). It did not appear to be getting worse at the time.

Could this be that scar getting worse? Or perhaps just a symptom of my usual eye strain (so far I've had burning in the back of both eyes all day long, tension headaches, migraines, nausea. All since last August, conditions worsening, then peaking at around November, where they appeared to have hit the top of the pain plateau). Maybe I have herpes in my eye somehow (I do suffer from fever blisters periodically; perhaps that type of herpes can spread to the eye? I haven't had a blister since sometime before the genesis of my chronic eye strain though).

Thanks!
